摘要：

Cu Cr alloys containing Cr from 0.14% to 2.0% in mass were prepared as foils for TEM observation before and after being extruded. The results show that before extrusion, the spheroid or short bar chromium disperse in copper matrix of the Cu Cr alloy, and the relationship between Cu and Cr follows the Nishiyama Wasserman (NW) relationship, i.e. [110] Cu ∥ [001] Cr . After the Cu Cr alloy was extruded at 860 ℃, dark field image along (224) Cu clearly shows that there are precipitated chromium particles in copper matrix. However, the SADP comprises only (112) Cu zone.
